ZildjianL80 Low Volume Cymbal Pack - LV468 w/Remo SilentStroke Heads

Q: Can I get 2 14" heads instead of a 14" and 16"?

I ended up buying a separate additional 14’ because I was in the same boat. So short answer is no

Q: I have sabian sbr and remo pinstripe should I change

If you're goal is to practice and either don't mind switching between heads or just want to set up a quiet drum set that won't bother people as much then I'd say go for it

Q: what size drum heads does it come with?

Includes: 10", 12", 14", 16", & 22" Silentstroke Drumheads

Q: What drumset should I get to use with this "Quiet Pack"

You should be able to use with most standard 5 piece drum kits. I have mine on an 80s Ludwig kit and my son has it on his 60s Rogers kit. Confirm the drum sizes match the drum heads in the pack before you purchase, just to be certain.
